Madrona 4.1 released

Since the initial release of Madrona 4.0, we have been working on many projects with 2D mapping interfaces (OpenLayers or Leaflet).
Much of the work to the Madrona core is related to the Enhanced 2D Layer Management
which allows knockout-based Javascript client apps to seamlessly incorporate advanced mapping interface elements.

Updates in the 4.1 release include:

New layer_manager app for managing 2D tiled map sources

By default, enforce_supported_browser set to False (may cause minor change in browser detection behavior in some 3D apps)
